NFC Wireless Charging Coming Soon to IoT Devices and Wearables

NFC Wireless Charging

NFC is better known for contactless payment and transferring contacts, but one interesting feature is the ability to provide power as we’ve recently seen with batteryless NFC powered E-paper displays. The current NFC implementations can only provide a limited amount of power, but the NFC Forum has recently approved the Wireless Charging Specification that enables wireless charging of small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. One watt is not as much as other similar technologies, but NFC wireless charging (NFC WLC) should be quite more cost-effective since device-specific wireless chargers are not needed. Just take a phone or charger with NFC WLC and all compliant devices could be charged that way. The specification is free to download for NFC Forum members but must be purchased by others. There’s still short abstract available: Wireless Charging allows for wireless charging of small battery-powered devices like …

TransferFi Wireless Power Network Lights Up Sensors up to 55 Meters Away

TransferFi

Wireless charging has been around for a while, and it usually placing a phone or other device on a charging pad. But back in 2018, Energous started to promote its near-field, mid-field, and far-field wireless charging solutions, with far-field meaning within a room. But so far, they only have released near-field devkits and products. Singapore based TransferFi Pte has come up with its own wireless charging solution. TranferFi wireless power network (TFi WPN) aims to power sensors up to 55 meters away and specifically targets building and factory automation in order to help companies save on installation and cabling costs. The solution works with a gateway powering up and receiving data from sensors wirelessly with a range of up to 55 meters.  The TFi Gateway Max Turin-1 covers up to 32 TFi Sense devices via multichannel beamforming supporting up to 16 channels and can be connected to Modbus, BACnet & Web services. The TFi Sense Turin-1 sensor node is powered …

ONiO.zero offers a RISC-V Microcontroller that runs without battery

ONiO.zero

Energy harvesting has been an exciting area people have tried to venture into mostly because of the possible applications that can arise from it. Newly invented energy-harvesting technologies accompanying low-power computing systems have pushed the boundaries of where embedded systems can be deployed. The demand for an increase in connected applications which require an underlying embedded system, and as we know, all electronic devices require a power source of some sort. This power source, batteries in most cases, comes with an accompanying buck regulator of some sort that will tend to increase the BOM. Aside from the BOM rise from the usage of batteries, there is also the shelf life and environmental aspects. The Norwegian specialist ONiO has introduced the ONiO.zero to address those issues. Having no battery means fewer components and a smaller design, which can easily be integrated into a wide range of solutions – be it fabrics, jewelry, watches, wearable medical devices, livestock or building sensors.

Energous Launches WattUp Smart Glasses Developer Kit for Customer Product Designs

The WattUp Smart Glasses Developer Kit

Near-field wireless charging technology has the potential to disrupt the consumer electronics industry, but its adoption has been limited. Energous wireless charging technology WattUp has promised to change that narrative by making it possible to charge devices mid-field (on the desk) or far off (in the room. Aside from the distance challenge in wireless charging, one other major issue is the fact that there are few deployments with them. Only a few devices have wireless charging incorporated. Energous is hoping to change that as well with the launch of the WattUp Smart Glasses Developer Kit, which is tailored for custom product design in the wearable industry. Energous is continuing its trend of launching a developer kit after having released the WattUp Hearables Developer Kit with Near-Field Wireless Charging and support for the SKIIN Smart Underwears. According to the Energous, the goal of the smart glasses developer kit is: Designed to ease manufacturers’ integration of WattUp into smart glasses, the new …

Energous Launches WattUp Hearables Developer Kit with Near-Field Wireless Charging

WattUp Hearables Developer Kit

We previously wrote about Energous WattUp near, mid, and far-field wireless charging while covering SKIIN smart underwears that could be recharged using WattUp near-field wireless technology, but the technology inside can also support future on the desk (mid-field) or in the room (far-field) charging. The company has now introduced the WattUp hearables developer kit that sadly still does not seem to support mid- and far-field charging yet but provides everything to manufacturers to get started with wireless charging for Bluetooth earbuds, smart headphones, and similar gadgets. The kit offers all hardware and software resource to get started with developing wirelessly charged audio devices: Transmitter reference design with power supply, based on Dialog Semi DA14680 Bluetooth LE chip, DA4100 wireless power transmitter, as well as EN3921 and EN3913M front end ICs. Receiver reference design with DA2223 RF to DC receiver and DA14585 Bluetooth LE SoC Mobile app Reference design user guide Datasheets Transmitter schematic and layout Receiver schematic and layout Software …

R-TV BOX S10+ is an Android 8.1 TV Box with a Built-in Qi Wireless Charger

S10-R-TV-BOX-Wireless-Charging

A couple of years ago we wrote about ECS Live Station, an Intel Bay Trail mini PC with an integrated wireless charger that can be used to charge any compatible smartphone. But as I was checking out new arrivals feed, I found out there was now a TV box that does the same thing. Apart from the wireless charger placed on top of the device, R-TV BOX S10+ is pretty much a standard 4K TV box based on RK3328 processor: SoC – Rockchip RK3328 quad core Cortex A53 processor @ 1.5 GHz with Mali-450MP GPU System Memory – 4GB RAM Storage – 32 GB eMMC flash + micro SD card slot Video Output – HDMI 2.0a up to 4K @ 60 Hz with HDR10 and HLG support, 3.5mm AV port (composite) Video Codec – 4K VP9, H.265 and H.264. 1080p VC-1, MPEG-1/2/4, VP6/8 Audio – Via HDMI, AV port (stereo audio), and 3.5mm coaxial S/PDIF jack Connectivity – 10/100M Ethernet, …

SKIIN Smart Underwears Support Energous’ WattUp Near, Mid, and Far-Field Wireless Charging

Near-field wireless charging has been around for several years, but for wireless charging to become really disruptive it needs to work at a distance, and Energous has been working on mid and far-field technology with their WattUp transmissive to charge devices respectively on the desk (mid-field) or in the room (far-field). You need to have compatible devices to work with the technology, and wearables are a prime target, but I was expecting fitness trackers or smartwatches to embed the technology at first, but instead one of the first WattUp compatible wearables are smart underwears from SKIIN. The module found in SKIIN underwears and bras have many of the same features as your typical fitness tracker, and some extras: Sensors ECG sensors for Heart Rate monitoring (HRM) Accelerometer and Gyroscope to measure motion & posture BIA (Bioelectrical impedance analysis) to monitor water intake levels and how your sweat affects your hydration, as well as you body fat levels Knitted Strain Gauge …
